The research, which was carried out by Dietmar Nedbal and Mark Stieninger of The University of Applied Science Upper Austria, focuses on the case of an Austrian SME specializing in the production of safety boots. The company switched from a paper- to an e-invoicing system offered through a cloud-computing solution provider on a 'software as a service' (SaaS) basis. Nedbal and Stieninger have calculated that a complete switch to e-invoicing has the potential to reduce costs by up to 62 percent and slash the related carbon footprint by over half.
